ASSIG-HOE TO EDlll'UND ELECTRIC LIQUID HEATER.

application filed July 2, 19:31.

To all whom may concern Be it known that l, F.- (lnono llrssnnr, a citizen of tllB Saxony, Germany, residing at Chcnmitz, I

the hepublic oi Saxony, Germany, have vented certain new and useful .lni ments in Electric Liquid Heaters, of i the following is a specification.

This invention relates to e ectifor heating water or other liqui are utilized to furnish the necess once to produce the heat in a liquid ch arranged between electrodes. The ob of my improvements are, first, to pro riproper flow of the liquid through thc s chamber; second, to prevent a rev-oi movement of the liquid in the said chem v third, to reduce the mixin of fresh co liquid with the already heated liqu d fourth to arrange the liquid 2 without perforating the electrode ing the liquid receiving chamb r.

I attain these objects by he tion illustrated in the accomp .nying drawing, in whichh Figure l is a longitudinal section of the device; Fig. 2, a cross section on the line A-A of Fig. 1; Fig. 3, a longitudinal section of a detail on an enlarged scale; a view of a detail.

The liquid, for example water, is introduced into the heater through a pipe which is connected to a nozzle (Z secured to iiic; electrodes f and g which inse inside the other, the nozzle (Z extendirg the bottom 7:: upwardly into an oblon pression at the inside of the electrode 7" n i being directed obliquely in an upward d.

rection against the inner electrode 5 outlet aperture 6 of the nozzle (Z is late-roll. arranged and prolonged in the lEOTll1 O slot arranged longitudinally of the hour chamber. A discharge pipe It is connecteto an opening arranged diagonally opposite the aperture 6 of the annular chamber:

screw 6 while it is provided with a rubber ted one i from The electrodes and 5/ are combined with plates 79 for the electrical connection an insulated from one another by me: rings a at their upper and lower siectively, and are made liquid tight by means oi. washers m which form supports of and also insulate the cover 2' and bottom 0 from the electrodes 7" and g, the said cover i and bottom 0 being pressed on the electrodes by means 01 a screw bolt 0, In the l =ing a there is a gauze 5- provider, by means oi which impurities are prevented il'Olll entering the heater. The fluid heater is preferably screwed to a marble slab Z.

The action of the apparatus is as follows.

The water introduced through the pipe at to the nozzle (Z is conducted by the nozzle (Z an oblique upward direction against the inner electrode 9'. The jet of the water breaks against the wall of the electrode 9 and forms a broad two armed cross current, of which one arm flows to the left and the or to right half of the electrode g, while at the same time, in consequence of the oblique direction of flow, an upwardly directed liquid pressure is set up which prevents backward movement of the already heated water in the upper part of the annular chamber. The fresh water does not i in with the already heated water, but forces the latter uniformly towards the outlet aperture of the annular chamber which connected with the discharge pipe it, it itself heated by the electric current The water is heated up to boiling, and may, in suitable quantities be drawn oil from the apparatus continuously in a boiling condition.

i ll

aware that prior to my invention heaters have been made with two ctr c electrodes leaving suitable space for the of water within the outer electrode.

1 therefore lo not claim such a communicaou broadly; but I claim:

1. The combination, in an electri uid receiving chamber surrounded by means? and against the said central electrode, all

of a cylindrical outer electrode, having at its inside an oblong depression extending upwardly from the bottom end of the said outer electrode, with a nozzle extending through the bottom upwardly into the said depression, said nozzle communicating with the said liquid receiving chamber by means of a lateral liquid discharge opening and adapted to lead the liquid from the bottom upwardly and against the central electrode, all substantially as set forth.

3. The Combination, in an electric heater, of a central electrode within a liquid receiving chamber surrounded by means of a cylindrical electrode, having at its inside an oblong depression extending upwardly from the bottom end of the said outer electrode, with a curved liquid inlet-socket extending through the bottom of the said liquid chamber into the said depression and having a lateral slot-shaped discharge aperture adapted to lead the liquid upwardly substantially as set forth.

4:. The combination, in an electric; heater, of a central electrode within a liquid receiving chamber surrounded by means of a cylindrical electrode, having at its inside an oblong depression extending upwardly from the bottom end of the said outer electrode, with a curved liquid inlet-socket extending through the bottom of the said liquid chamher into the said depression and having a lateral slot-shaped discharge aperture adapted to lead the liquid upwardly and against the said central electrode, and a gauze arranged in the said aperture, all substantially as set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.
